Rotate point B about point F 288 degrees clockwise

Mathematics

algol [13]2 years ago

When a shape is rotated, it must be rotated through a point

The new position of point B is point A

The angle of rotation is given as:

Angle = 288^o

The shape is a regular pentagon (with 5 sides).

The smallest angle of rotation that maps the pentagon onto itself is calculated using:

\theta = \frac{360}n

So, we have:

\theta = \frac{360}5

\theta = 72

Let the number of rotations be n.

So, we have:

\theta \times n= Angle

This gives

72 \times n= 288

Divide both sides by 72

n= 4

This means that the new position of B is 4 points away from B.

Point A is 4 points away from B, in clockwise direction

Hence, the new position of point B is point A

Write the equation of the circle whose center is (-4,8) and has a diameter of 18
svetoff [14.1K]

Answer:

(x + 4)^2 + (y - 8)^2 = 81

or

(x + 4)^2 + (y - 8)^2 = 9^2 depending on how your teacher wants it written.

Step-by-step explanation:

The standard form for a circle is

(x + h)^2 + (y + k)^2 = r^2

r is the radius.

You are given the diameter

r = d/2

r = 18/2

r = 9

So you already have the right hand side of the equation

(x + h)^2 + (y + k)^2 = 9*2

(x + h)^2 + (y + k)^2 = 81

You basically have h and k as well. They come from the center point.

h = 4

k = - 8

So the equation of the circle (and the answer) is

(x + 4)^2 + (y - 8)^2 = 81

One question remains. Why do the x and y values change signs? If you know what the distance formula is, then what you are finding is the distance r of all points on the circle from the center of the circle.

It is the distance formula that is actually the formula for the circle.

You have a coupon for an additional 25% off the price of any sale item at a store. The store has put a watercolor kit on sale fo
telo118 [61]
Final price=original price*(100%- discount 1)(100%-discount 2) 
original price=$40
discount 1=25%⇒         100 - discount 1=100%-25%=75%=75/100=0.75
discount 2=15%⇒         100 - discount 2=100%-12%=85%=85/100=0.85

original price=$40(0.75)(0.85)=$25.5
